Strange Boot Behavior

["Stephen P. Molnar" <s.molnar@sbcglobal.net>]

I have Debian 12 installed on my main computer.

This morning, when I booted the computer , I got "GRUB ERROR>"  and the 
message that there was no operating system on the boot SSD.

Fortunately, I have Debian 12 installed on two SSD's on the platform. I 
shut down the computer, restarted it with F2 to open the BIOS and 
selected  the other SSD with Debian. When GRUB came up I was presented 
the normal selection screen, The booting process continued normally with 
the SSD that gave me the "GRUB ERROR>" initially.

Then I shut down the system and restarted it. Normal start up!!!!!!!!!!

Does anyone have any ideal as to what might be going on (yes, I know an 
impossible question)?
